GitHub Actions — Your First Automated Pipeline
Build a real CI/CD pipeline with GitHub Actions, from your first workflow file to caching, artifacts, and parallel jobs.
In the last lesson, we talked about what CI/CD is and why it matters. Now let's build one.
GitHub Actions is the CI/CD platform built directly into GitHub. If your code lives on GitHub — and for most of us, it does — Actions is the obvious choice. No separate service to sign up for, no third-party integration to configure, no additional billing to manage. It's just there, waiting for you to write a YAML file.
How GitHub Actions Works
GitHub Actions is event-driven. You define workflows that respond to events. An event is something that happens in your repository — a push, a pull request, a release, a scheduled time, even a manual button click. When an event fires, GitHub spins up a virtual machine, runs your workflow, and reports the results.
